How to change display scaling settings in Lubuntu?

Question

How to change display scaling settings in Lubuntu, so that the font, the icons and the buttons are bigger, similar to Mac OS X, in size?

Answer 1

In Lubuntu 21.10, I had to go through the following steps:

1. Open LXQt Configuration Center -> Session Settings -> Environment Variables (Advanced) or run lxqt-config-session
2. Add QT_SCALE_FACTOR with value 2
3. Add GDK_DPI_SCALE with value 2
4. Add XCURSOR_SIZE with value 64

5. Open LXQt Configuration Center -> Appearance -> Font and set Resolution (DPI) to 192

LXQt now has a global screen scaling option on the 'session settings' as directed above. Set it to 2, or in my case I am on a different monitor
